    • A Parallelizing Compiler Based on Partial Evaluation 

      Surati, Rajeev (1993-07-01)
      We constructed a parallelizing compiler that utilizes partial evaluation to achieve efficient parallel object code from very high-level data independent source programs. On several important scientific applications, ...
    • Parameter Estimation in Chaotic Systems 

      Hung, Elmer S. (1995-04-01)
      This report examines how to estimate the parameters of a chaotic system given noisy observations of the state behavior of the system. Investigating parameter estimation for chaotic systems is interesting because of ...
    • Passive and Active Grasping with a Prehensile Robot End-Effector 

      Greiner, Helen (1990-05-01)
      This report presents a design of a new type of robot end-effector with inherent mechanical grasping capabilities. Concentrating on designing an end-effector to grasp a simple class of objects, cylindrical, allowed a ...
    • Passive Dynamics in the Control of Gymnastic Maneuvers 

      Playter, Robert (1995-03-01)
      The control of aerial gymnastic maneuvers is challenging because these maneuvers frequently involve complex rotational motion and because the performer has limited control of the maneuver during flight. A performer can ...
    • Performance Evaluation of the Scheme 86 and HP Precision Architecture 

      Wu, Henry M. (1989-04-01)
      The Scheme86 and the HP Precision Architectures represent different trends in computer processor design. The former uses wide micro-instructions, parallel hardware, and a low latency memory interface. The latter ...
    • The PHD: A Planar, Harmonic Drive Robot for Joint Torque Control 

      Thompson, Bruce R. (1990-05-01)
      This thesis details the development of a model of a seven degree of freedom manipulator for position control. Then, it goes on to discuss the design and construction of a the PHD, a robot built to serve two purposes: ...
    • Pi: A Parallel Architecture Interface for Multi-Model Execution 

      Wills, Donald Scott (1990-05-01)
      This thesis defines Pi, a parallel architecture interface that separates model and machine issues, allowing them to be addressed independently. This provides greater flexibility for both the model and machine builder. ...
    • Piezoelectric Ultrasonic Micromotors 

      Flynn, Anita M. (1995-06-01)
      This report describes development of micro-fabricated piezoelectric ultrasonic motors and bulk-ceramic piezoelectric ultrasonic motors. Ultrasonic motors offer the advantage of low speed, high torque operation without ...
    • PILOT: A Step Toward Man-Computer Symbiosis 

      Teitelman, Warren (1966-09-01)
      PILOT is a programming system constructed in LISP. It is designed to facilitate the development of programs by easing the familiar sequence: write some code, run the program, make some changes, write some more code, ...
    • Planning and Teaching Compliant Motion Strategies 

      Buckley, Stephen J. (1987-01-01)
      This thesis presents a new high level robot programming system. The programming system can be used to construct strategies consisting of compliant motions, in which a moving robot slides along obstacles in its ...
    • Planning for Conjunctive Goals 

      Chapman, David (1985-11-01)
      The problem of achieving conjunctive goals has been central to domain independent planning research; the nonlinear constraint-posting approach has been most successful. Previous planners of this type have been comlicated, ...
    • A Planning System for Robot Construction Tasks 

      Fahlman, Scott E. (1973-05-01)
      This paper describes BUILD, a computer program which generates plans for building specified structures out of simple objects such as toy blocks. A powerful heuristic control structure enables BUILD to use a number of ...
    • Pose Determination of a Grasped Object Using Limited Sensing 

      Siegel, David M. (1991-05-01)
      This report explores methods for determining the pose of a grasped object using only limited sensor information. The problem of pose determination is to find the position of an object relative to the hand. The information ...
    • Pose-Invariant Face Recognition Using Real and Virtual Views 

      Beymer, David (1996-03-28)
      The problem of automatic face recognition is to visually identify a person in an input image. This task is performed by matching the input face against the faces of known people in a database of faces. Most existing ...
    • Predicate Dispatching in the Common Lisp Object System 

      Ucko, Aaron Mark (2001-05-01)
      I have added support for predicate dispatching, a powerful generalization of other dispatching mechanisms, to the Common Lisp Object System (CLOS). To demonstrate its utility, I used predicate dispatching to enhance Weyl, ...
    • Presentation Based User Interface 

      Ciccarelli, Eugene C., IV (1984-08-01)
      A prototype presentation system base is described. It offers mechanisms, tools, and ready-made parts for building user interfaces. A general user interface model underlies the base, organized around the concept of a ...
    • Principle-Based Parsing 

      Berwick, Robert C. (1987-06-01)
      During the past few years, there has been much discussion of a shift from rule-based systems to principle-based systems for natural language processing. This paper outlines the major computational advantages of ...
    • Probabilistic Analysis of Multistage Interconnection Network Performance 

      Sobalvarro, Patrick G. (1992-04-01)
      We present methods of calculating the value of two performance parameters for multipath, multistage interconnection networks: the normalized throughput and the probability of successful message transmission. We develop ...
